Myelodysplastic neoplasms (MDS) are clonal disorders of the myeloid lineage leading to peripheral blood cytopenias. Dysregulation of innate immunity is hypothesized to be a potent driver of MDS. A recent study revealed increased thrombomodulin (TM) expression on classical monocytes in MDS, which was associated with prolonged survival. TM is a receptor with immunoregulatory capacities, however, its exact role in MDS development remains to be elucidated. In this review we focus on normal monocyte biology and report on the involvement of monocytes in myeloid disease entities with a special focus on MDS. Furthermore, we delve into the current knowledge on TM and its function in monocytes in health and disease and explore the role of TM-expressing monocytes as driver, supporter or epiphenomenon in the MDS bone marrow environment.

Myelodysplastic syndromes (MDSs) are a group of hematologic neoplasms accompanied by dysplasia of bone marrow (BM) hematopoietic cells with cytopenia. Recently, digitalized pathology and pathomics using computerized feature analysis have been actively researched for classifying and predicting prognosis in various tumors of hematopoietic tissues. This study analyzed the pathomic features of hematopoietic cells in BM aspiration smears of patients with MDS according to each hematopoietic cell lineage and dysplasia.

partial tandem duplication (PTD) involves intragenic duplications and has been associated with poorer prognosis. In this study, we evaluated PTD in 1277 patients with hematological malignancies using optical genome mapping (OGM). PTD was detected in 35 patients with acute myeloid leukemia (AML) (7%), 5 patients with myelodysplastic syndrome (MDS) (2.

Article Synopsis
- Tandem duplications (TDs) in the UBTF gene are a recently identified genetic alteration linked to pediatric and adult acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS), establishing UBTF-TD as a distinct subtype of AML.
- A study of 27 pediatric patients revealed that UBTF-TD is commonly associated with symptoms like cytopenia and characteristic changes in bone marrow, such as erythroid hyperplasia and trilineage dysplasia.
- The findings suggest that patients with MDS and AML exhibiting UBTF-TD have similar prognoses, indicating that both conditions may represent different manifestations of the same underlying disease.

Article Synopsis
- Chronic myelomonocytic leukemia (CMML) is a complex blood cell disorder that combines poorly functioning and overproducing blood cells, leading to various symptoms.
- The case study focuses on a 71-year-old man with severe CMML who experienced skin nodules that improved with treatment but later recurred, while avoiding progression to acute leukemia.
- The findings emphasize the importance of close monitoring and flexible treatment approaches for patients with CMML, especially those with skin involvement.
